TOBACCO STRIPPING AND BOOKING MACHINE.

SPECPICA'ICN forming part of Letters Patent No. 317,794, dated August 24, 18C 6.

. Application filed February 23, 15186.

To all whom it may concern.'

Be it known that I, OSCAR H AMMERSTEIN, a resident of New York city, in the county and Stateof New York, have invented an Improved Tobacco Stripping and Booking Machine, of which the following is a t'ull, clear, and exact description, reference being madeto the accompanying drawing This invention relates to a new machine for stripping tobacco-that is, cutting the central stem ontot' each leaf ot' tobacco-and for booking the same.

One object ofthe invention is lhat the mav chine, in addition to cutting out the stems nicely and rapidly, shall also place the stripped leaves one upon another in proper manner. This object I accomplish by means of a rotating drum, which operates in combination with endless bands, that are held under tension, and with the stripping meehair ism proper in such manner that the two halves of each leaf, ai'ter the stripping has been performed,will be placed upon the outer periphery of the drum beneath the endless band, and that as the machine operates upon the successive leaves their respective halves will be piled one upon another around said drum, all as hereinafter more fully described. The booking contrivance can be used without the stripping mechanism.

Theinvention consists of the novel combination of parts hereinafter described.

Figure l is a side elevation of myimproved tobacco stripping and booking machine. Fig. 2 is a vertical cross-section of the machine, taken on the planeof theline c c, Fig. 4;. Fig. 3 is a similar section on the line lc k, Fig. 4. Fig. 4 is a front elevation of the machine. Fig. 5 is a longitudinal central section ofv the two drumsthat carry the stripped tobacco. Fig. 6 is a sectional View of the shafts that carry the saws, and the flanges near the same. Fig. 7 is a top view of the same. Figs. 8 and l0 are side views of the clutch mechanism used on the machine; and Fig. 9 is atop view ofthe same.

In the accompanying drawings, the letter A represents the frame of my improved machine, which franie is by preference of the i'orm outlined in Figs. 1, 2, and 3. In this frame are the bearings of a horizontal shaft,

Serial No. lll-2,958. (Nomade/l.)

B, which shaft is immovable, and which carries four (more or less) stationary rings, C, around which are placed two drums, D D, as

appears more clearly from Fig. 5 of the drawings. The rings C beingstationary, the drums D are intended to rotate around said rings, and thesedrums have on their inner peripheries suitable annular rails, n., that fit around the peripheries of the rings C, and that are flanged to prevent longitudinal displacenient of each drum on its supporti ng set ot' rings C. Each drum l) contains in its interiora toothed ring. b-that is, a ring which has its teeth cnt on the inner periphery. The teeth maybe on one ot'the annular rails a, as in Fig. 5. Into these two toothed rings b b mesh the teeth of pinions (Zd, that are mounted upon a drivingshalt, E, which drivingshal't has its bearings likewise in the frame A of thc machine, and causes the drums to rotate whenever such rotation is desired, and tostop whenever its own motion is arrested.

To the upper part ot' the frame A is hinged at e an upper frame or lid, F, which can be let down into the position shown by full lines in Figs. l, 2, and 3, or turned up into the position shown by dotted lines in Fig. 3.

G is an endless belt or band,made ot' indiarubber or of any other suitable analogous substance, there being one such band i'or each of the drums D, each band being about as wide as the drum is long, and adapted to encircle the drum in the manner shown in Fig. 3, and as hereinafter more fully stated-that is to say, the endless band passes over rollersf, g, and h, that have their bearings in the frame A,and over rollers i and j. that are supported by the lid F, and over rollers Z and m, that are hung in a movable frame, J, all as shown in Fig. 3. The rollersf and m are, when the lid is down, rather near together on the same side of the drum D, and the band G, which is represented by a heavy black line in Fig. 3, passes around the drum D, excepting that portion thereof which is between the rollersfand m. Around m the band G passes and extends upward to t-he roller Z, thence to j, t-hcnce to fi, and from there down. The band,al'ter passing around the roller f, passes downward around g, thence around l1., and then down, it forming a loop in its lowcrniost part, in which a IOO weighted roller, H, is hung. This weighted roller has for its object to keep the band G tight, and at the same time to allow it to yield to the leaves of tobacco that accumulate between the drum D and the band G. Thus in Fig. 3 a great many leaves of tobacco are shown at I,to be interposed between the drum and the band, while in Fig. 2 no leaf of tobacco is 'shown between the drum and the band. It follows, therefore,that in Fig. 3 the weighted roller H is raised higher than it is in Fig. 2.

So far as the booking ofthe tobacco in the machine is concerned, the intention is to place leaf upon leaf on each drum D, and to keep the pile of leaves compressed by the outer` band, G. How this can readily be accomplished will be understood by reference to Fig. 3. In this figure the drum D is not represented in the position of rest, but in the position in which it is after having been turned in the direction of the arrow 1, a short distance from the position of rest. Several leaves of tobacco are already held on the drum beneath the band G, as represented at I in Fig. 3. A new leaf (shown at 12) is being taken along by the drum as the same revolves in the direction of the arrow l, the drum crowding the point of the new leaf 12 against the point of a leaf, I, already booked, the ends of both leaves being between the drum and the band-that is, that portion which eX- tends from the roller faround the drum. It will be readily seen that-asthe drum continues to revolve in the direction of the'arrow l the new leaf l2 will bc taken along and placed upon the pile of leaves l, and introduced at the same time between the drum and the outer band, G, the weight H holding the band tight against the tobacco; hence this machine does not coil the leaves of tobacco in a continuous convolution around the drum or roller, as has been done in previous machines; but it books the tobacco by placing leaf upon leaf on the drum and holdingthe whole pile of leaves under pressure of the band G. The register of the leaves is obtained Aby the automatic stopping of the rotation of the drum at the c nd of each revolution or other unitof motion. After the proper number of/leaves of tobacco have been piled upon the drum, as in Fig. 3, they can be readily removed by simply turning up the hinged lid F into the position shown by dotted lines, thereby lifting the upper part of the band G 01T the leaves and disclosing them ready for convenient removal. Ot' course it is perfectly evident that as the drum is revolved in the direction of the arrow l the endless band G, which partly embraces such A drum, will, by frictional contact therewith, be

carried around at the same rate of speed, the sund ry arrowsin Fig. 3of the drawingsshowing the direction in which the band rotates whenever the drum is turned in the direction ofthe arrow l. The rollers l and m, which, as has been stated, are in part embraced by the band G, have their bearings not directlyinthe cover anism.

F, but in a frame, J', which is movable on the cover F, so that both rollers l and m may be crowded away from the drum D. Thus in Fig. 3 of the drawings it is shown that said rollers are crowded'off the drum D by the six thicknesses of leaf I, which lie on said drum. The more tobacco there is booked upon said drum the farther will the rollers l and m. be crowded away from the drum,the movable frame J permitting this motion. Meanwhile the weight H, by holding the band G under tension. serves to crowd the rollersl m as near to the drum as possiblethat is to say, as near as the intermediate leaves of tobacco will permit; hence the leaves of tobacco are always held on the drum under pressure of the band, and yet the machine is, by virtue of these movable rollers l m, suiciently flexible to be adapted to receive a suitable number of leaves between the drum and the band.

In the drawings I have represented the mov able frame J to be provided with projecting end lugs, a, which are guided in slots 0, that are formed in ears p of the covcr,F, so that the outward motion of the rollersl 'm and their frame J will be in the direction permitted and to the extent allowed by the said slots o.

\Vhcnever the cover is to be lifted into the dot-ted position shown in Fig. 3, it is grasped by means of a rod, r, which connects with the. ears p, and serves as a handle for moving said cover.

Having now described the general princil'OO ples ofthe booking mechanism of my improved y machine, l will proceed to describe the means of feeding the leaves of tobacco into the machine and of stripping the same; but l desire it to be understood that althbugh this machine is represented as a stripping-machine and a booking-machine combined, nevertheless the features ofthe booking mechanism may be cmployed independently of the stripping mech- This stripping mechanism consists of two rotary saws, L L, which are mounted upon a shaft, M, that has its bearings in the frame A. Rotary motion is imparted to the shaft M by aseparate belt, a2. and pulley b2, orothcr suitable mechanism. The two saws L L are placed, as shown in Fig. 4, between the two drums D D, and as far apart from one another as is necessary for the portion that is to be cut out of the leaf. The leaf l2 may be fed to the machine over a small platform, N, (shown by dotted lines in Fig. 3,) which is affixed to the front portion of the frame A, slightly above the level of the rollerfand directlyin front of said roller. The motion of the band G when the machine is in operation, together with the motion of the drum D, will, after the point or end ofthe leafshall have been introduced prop erly between said drum and band, cause the leaf to be grasped by them and moved along in the direction of the arrow 1, which is rcp resented in Fig. 3.`

From an arm, s, which is attached to a cross-bar, t, of the frame A, is suspended, as appears from Fig. 2, a rod, O, which is be- IIO tween thetwo saws L L, in front of their shaft M, and which reaches down below said saws, all as shown in Fig. 2. The object ot' this rod is to prevent the vei n of tobacco which is cut out ot' the leaf by the two saws from becoming entangled with the shaft M, the said rod O guiding the vein downwardly and causing it to be discharged at the lower front portion of the machine. By front portion 7 I mean that part ot' the machine in which are cont-ained the rollers j' and m. Instead of this rod O, a loose ring on the shalt M, between the saws, may be used. For the purpose of preventing this vein from being displaced lat erally,I place the twosaws L L between two disks, a, which are mounted upon a shaft, P, that is hung in the frame A beneath the shaft M. The shat't l is revolved by a band, di, which connects it with the shaft E. The disks u,which straddle the saws L, as is more clearly shown in Figs. 2, 6, and 7, guide the sides of the cut out vein, so as to prevent the latter from being displaced laterally, and, together with the suspended rod O, force the vein that is cut g from the leaf to drop downwardly. The saws L L enter with their front portionsinto `grooves that are formed in the roller f, as shown in Fig. 7. so that the leaf I, as it feeds over the rollerf, will meet the saws while it is still on the roller. The weighted roller H is connected by a chain, w, with an arm, ce, on the cover F, so that whenever said cover F is swung back on its pivot e, as by dotted lines in Fig. 3, the roller H will be lifted and the band GA made slack to a sufficient extent to prevent it from interfering` with the raising ofthe cover.

lt remains to show 4how theintcrmit-tcnt rtary motion of the drums D is insured. I have already stated that these drums are revolved by the toothed connection with the drivingsha-ft E. This drivingshaft carries a driving-pulley, y, with which connects a belt or other mechanism for turning it, but this drivingpnlley is loose on the shaft E, and is connected therewith, only so as to impart rotary motion, by means ot aclutch, R. /Vhen this clutch is oifthe pulley, as in Fig. 10, the shaft E will not be revolved. Vhen it is on the pulley, as in Figs. 8 and 9, the shaltE will be revolved.

To get the .clutch on the pulley and start the rotationof the drains, the machine is provided with a treadle, S, that connects by a rod, z, with a disk, which disk is hungin theframe. A, and which connects by an arm, f2, with a forked lever, T, that straddles the clutch R, engaging therewith where said clutch is grooved for the purpose. Then the treadle is depressed, the rod z is raised and the disk c2 turned from the position which is shown in Fig. l0 in the direction ofthe arrow 2 iutothe position which is shown in Fig. S. By this motion of the disk the arm fgis pushed along, so as to move the forked lever T and carry the clutch against the pulley, the contact-faces of cl utch and pulley being toothed in the ordinary manner. A spring, g2, connects the frame A with the disk ci, its point of connection with the disk being such that in order to ca-rry the disk from the position shown in Fig. l0 to the position shown in Fig. 8 this point must pass vertically below the center of the disk, in which position the spring will be most compressed; hence when thetreadle has succeeded in turning the disk eiso far asto bring the point of connection of disk and spring beneath the center of the disk,the spring will take up the rest ofthe work, and in expanding carry the disk farther into the position shown in Fig. 8. \Vhcn,after this,the shaft E is turned, and with it the drums D, to the proper extent-,thc clutch is again moved out of gear, and thereby the farther motion oftheshaft Earrestcd by aprojecLion. r, which is formed ononeol" the drums D, as shown in Figs. 5 aud S. This projection at the proper time will strike an ear, 2"", which is formed on the disk c2, and lifting this ear will turn thc disk back into the position shown in Fig. '10, the springg'Z again assisting in completing the last part of this backward movemeut of the disk. Thus the rotation ot' the drum is automatically arrested at the lvery point where the leaves of tobacco already booked will be ready to receive in proper position a new leafof tobacco to be booked.

I have represented in the drawings only one projection or stop, il?, on the drum D but it is clear that instead of making a con'lpleterevolutiou of the drum and then stopping. the machine, the mechanism can also be proportioned so that the machine can be stopped atter every hal f-rcvolution or third of a revolution of said drum, in which case a corresponding number of projections, 71.2, will be provided. v

In order to prevent the bands G from becoming displaced laterally as the leaves I accumulate on the drums D, I altix grooved guides WV to the frame A, as shown. There are at least two such guides to each band G- one for cach edge of such band. Instead of saws L L, other cutters of well-known description may be used.
